Materials Data on Ga3Ge by Materials Project

Abstract

Ga3Ge is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ga is bonded to eight equivalent Ga and four equivalent Ge atoms to form GaGa8Ge4 cuboctahedra that share corners with twelve equivalent GaGa8Ge4 cuboctahedra, edges with eight equivalent GeGa12 cuboctahedra, edges with sixteen equivalent GaGa8Ge4 cuboctahedra, faces with four equivalent GeGa12 cuboctahedra, and faces with fourteen equivalent GaGa8Ge4 cuboctahedra. All Ga–Ga bond lengths are 2.99 Å. All Ga–Ge bond lengths are 2.99 Å. Ge is bonded to twelve equivalent Ga atoms to form GeGa12 cuboctahedra that share corners with twelve equivalent GeGa12 cuboctahedra, edges with twenty-four equivalent GaGa8Ge4 cuboctahedra, faces with six equivalent GeGa12 cuboctahedra, and faces with twelve equivalent GaGa8Ge4 cuboctahedra.
